Data Page Tab Design for Enhanced Tear-Off Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data pages with attached tabs face difficulties in manipulation detection and durability due to one-sided tab connections, which lead to reduced tear-off strength and increased difficulty in ultrasonic welding due to differing hardness between the tab and the individual page.
Innovation Solution
The data page design features tab sections on both the top and bottom of the individual page, laminated or welded for enhanced tear-off strength, with a symmetrical arrangement and flexible connection areas to prevent one-sided peeling, using thermoplastic polymers and textile materials for secure adhesion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the tab is connected only on one side of the individual page, then the manufacturing process is simpler, but the tear-off strength is reduced and manipulation detection becomes difficult
Solution Approach 1:
The tab connection is segmented into two separate connection points: one on the top side of the individual page and another on the bottom side. This segmentation allows the tab to be distributed across both sides, increasing the total connection area and tear-off strength while maintaining manufacturing simplicity through standardized single-sided connection processes at each location.
Solution Approach 2:
The tab connection transitions from a single-sided (one-dimensional) connection to a double-sided (two-dimensional) connection arrangement. By placing tab sections on both the top and bottom sides of the individual page, the connection is distributed across multiple spatial dimensions, significantly increasing tear-off strength and enabling manipulation detection from either side.
2Strength
If the tab is connected on both sides of the individual page, then the tear-off strength is improved and manipulation detection is easier, but the manufacturing process becomes more complex
Solution Approach 1:
The complex double-sided connection is segmented into two independent, simpler connection operations: one tab section connected to the top side and another tab section connected to the bottom side. Each connection can be manufactured using standard single-sided processes, reducing overall structural complexity while achieving enhanced tear-off strength through the combined effect of both connections.
3Reliability
If ultrasonic welding is used to connect the tab to the individual page, then the connection is secure, but the process becomes more difficult due to differing hardness between the tab and individual page materials
Solution Approach 1:
The ultrasonic welding process applies local quality control by concentrating the welding action at specific tab section locations on both sides of the individual page. The welding parameters (pressure, amplitude, time) are optimized for the local material conditions at each connection point, allowing secure connection despite material hardness differences. The distributed two-point connection reduces the stress concentration at each weld point.
